Patek Philippe never set stones on a Cubitus, so this iced 5821 style super clone with a white dial and steel look is a factory creation from bezel to clasp. This white-dial replica Cubitus builds on the square sports case that marked a new chapter in the Patek Philippe catalog. Here the factory takes the steel 5821 shape, sets a baguette-cut stone bezel, pavé flanks and a fully stone-set bracelet in a white-metal look, and adds a white dial; Patek has no such reference, but the 45 mm square case with integrated bracelet still gives a silhouette with no precedent in the brand’s history. Launched in 2024, the genuine Cubitus challenges established square and octagonal sport watches from other houses by applying Geneva-level finishing to a bold, contemporary format. The white dial with horizontal embossed stripes and plain dark baton indices gives this variant a dressier personality compared to the other dial options in the range. Our guide weighs the iced 5821 versus the plain steel model for anyone undecided.

The horizontal embossed stripes across the dial create a ribbed surface that plays with light at every angle. The indices stay plain dark batons rather than stones, which keeps the white dial readable inside all the sparkle without cluttering the layout.

An All-White Watch From Bezel to Clasp

This bracelet is white metal throughout, with every link covered in small pavé-set stones, following the same visual logic as the iced case and continuing it all the way to the clasp. The octagonal bezel with its angled corners softens what could be an aggressive silhouette, and the integrated bracelet flows into the case without visible gaps. At 45mm measured corner to corner, the Cubitus wears larger than most Patek Philippe references. The blue dial 5821/1AR version offers the genuine two-tone colourway as a contrast to this white, stone-set combination. Both variants belong to the Cubitus range, which remains the newest addition to the sport-watch catalog.

How the 45 mm Diagonal Translates on the Wrist

The 45 mm measurement refers to the square case measured diagonally, so the actual lug-to-lug and width dimensions sit closer to what you would expect from a 42mm round watch. The bracelet is the part that changes most compared with the genuine steel Cubitus: every link carries stones, so it feels heavier and stiffer than plain steel. With stones on the bezel, flanks and bracelet, the overall effect is jewelry-forward rather than sporty, and the plain dark batons are what keep it a readable watch. As a replica Cubitus it trades the understated steel finish of the original for full sparkle, and the white dial makes it the most monochrome of the iced set.
